[PATCH] cron: Quietly abort if the package was removed

[Valters Jansons <valter.jansons@gmail.com>]

Previously, Debian was not installing the cron job. Now packaging it up
and alerts about the risk of `/usr/bin/location` not being available.

The scenario for this is that `/etc` contains configuration files, so
running `apt remove location` would leave the cron job hanging. If it is
a standard system with systemd, then the cron job expects systemd to
manage everything. However, if the system doesn't have systemd, then the
cron job will try to run a non-existant binary every day. This should be
gracefully handled.
